After crossing the marshland the aircraft collided with a 1.5 m high barrier on the side of a helipad. The aircraft stopped on the helipad at a distance of 880 m and 120 m to the left of the longitudinal axis of the runway.

Conclusion (translated from Russian):The accident without casualties to the aircraft An-12BK RA-11376 was the result of uncontrollability of the nose gear due to the failure of the nose landing gear control system in the taxi during takeoff and landing position due to failure of switch VG15-2S. The captain, in violation of FAP 128, did not control working the steering system of the An-12 in preparation for take-off and did not take measures to stop the takeoff roll.
